AMD started delivering on their word of providing GPU specifications to the open-source community without a Non-Disclosure Agreement, and now with the 2007 X Developer Summit having come to a close, we asked several key members of the X.Org community on how they judge AMD's recent move. They were also asked if they believe NVIDIA will follow suit in helping the open-source community. Those that responded were David Airlie, Daniel Stone, Jerome Glisse, Stephane Marchesin, and Oliver McFadden. Mark Shuttleworth had also previously commented on AMD's efforts.

Given enough time I'm quite sure that's gonna happen. I had a laptop before with R200 card integrated and it worked perfectly with the open-source drivers. And the drivers just kept on getting better. Now the devs have complete specs and won't have to do any guesswork, only code, so it seems likely your card will work some day
